Glutamic Acid
Glutamic acid is a gentle amino acid used in UK skincare and haircare to help moisturise, condition and balance the skin and hair. It is a popular ingredient in creams, serums, masks and shampoos for its ability to attract and hold water while softening the surface.
How it works in skincare
In cosmetics glutamic acid functions primarily as a humectant and skin-conditioning agent. It helps the skin and hair attract moisture from the atmosphere while improving softness and suppleness. Its lightweight nature makes it ideal for lightweight moisturisers, hydrating mists and conditioning hair products where it supports the skin’s natural moisture barrier without feeling heavy or sticky.
